PROBLEM TO BE SOLVED: To provide an ink jet recording device which gives a stable charge amount to a particle and which provides a stable print quality.SOLUTION: A print head comprises a nozzle which continuously forms ink into a particle and jets the ink, an orifice 9 through which the ink formed into particle and jetted from the nozzle passes, and a charge electrode which charges the ink particle having passed through the orifice 9. The charge electrode comprises: a block-like charge electrode block 10a; a charge electrode back cover 10b which is located between the charge electrode block 10a and the orifice 9, and fixes the charge electrode block 10a; and a charge electrode front cover 10c which is located on a side opposite to the charge electrode back cover 10b with respect to the charge electrode block 10a, and fixes the charge electrode block 10a. The charge electrode block 10a, the charge electrode back cover 10b and the charge electrode front cover 10c are integrally configured, and the charge electrode, and the orifice 9 and the nozzle are integrally configured.SELECTED DRAWING: Figure 1 【課題】安定した電荷量を粒子に与え、印字品質の安定したインクジェット記録装置を提供する。【解決手段】印字ヘッドは、インクを連続的に粒子化して噴出するノズルと、ノズルにより噴出した粒子化されたインク粒子が通過するオリフィス９と、オリフィス９を通過したインク粒子を帯電させる帯電電極と、を備え、帯電電極は、ブロック状の帯電電極ブロック１０ａと、帯電電極ブロック１０ａとオリフィス９との間に配置され帯電電極ブロック１０ａを固定する帯電電極バックカバー１０ｂと、帯電電極ブロック１０ａに対して帯電電極バックカバー１０ｂとは反対側に配置され帯電電極ブロック１０ａを固定する帯電電極フロントカバー１０ｃと、を備え、帯電電極ブロック１０ａと帯電電極バックカバー１０ｂと帯電電極フロントカバー１０ｃとが一体となり構成されており、帯電電極及びオリフィス９とノズルとは一体となり構成されている。【選択図】図１
